.'MANUFACTURE oF scoops.

SPECIFICATION forming part of Letters Patent No. 268,669, dated December 5, 1,882. Application filed August 14, 1882. (N o model.)

ofthe same, reference being had to the accompanying drawings, forming part of this specification, in which Figure I represents the :flat blade blank; Fig. 2, the blade with the projection at the top drawn out; Fig. 3, the blade with the back` Vstrap welded onto the projection; Fig. 4, the

blade with both front and back straps Welded on, but before being pressed up into shape; Fig. 5, a view of a completed scoop.

j Similar letters of reference in `the several figures denote the same parts.

One method of manufacturing metal scoops heretofore practiced consists in striking up from asingle piece of metal the blade and the back strap and then securing the front strap by means ofrivets; but the forming of the back strap continuous with the blade is somewhat expensive and the attachment of the front strap to the blade by means of rivets is objectionable, because the rivets wear and become loose. In another method heretofore practiced a piece of fiat metal with a V-sh aped portion cut out at the top is heated and pressed up into the shape of a scoop-blade, andthe front and back straps are also separately cut out and pressed to proper shape to lit the blade, and are then applied one at the front and the other at the rear of the blade,so as to cover the V-sh'aped space and leave room between them to receive the handle. This heilig done, the straps are fastened to the blade by means of rivets, the blade and straps are heated to welding heat, a mandrel is inserted between the two straps, and then by proper dies and pressure the straps are welded to the blade. This method `requires a good many dies and` alarge amount of machinery, and the resulting article is a scoop having a large front strap as well as a large iron back strap, the latter being especially exposed to wear when usin the scoop in coal, ore, Svc. It has been my ject to improve upon these prior methods and to produce at less trouble and expense form a small projection, a, of about one-fourth to one-half an inch in length at the top of the blade.

To this projection I weld Vthe narrow back strap, B, and to the front of the blade I weld the large front strap, G. The blade remains perfectly flat during the process of welding. I next heat the blade and insert a mandrel between the blade and the large front strap, C, in order to form a socket to receive the handle, and while the mandrel is still in position Iplace the heated blade between suitable dies, and by the application of power press the blade into shape; or I press the blade into shape rst, and afterward introduce the mandrel to open up the socket.

It will be observed that by my mode of manufacture a scoop is produced having a solid steel back, and that the V-shaped piece usually cut out is utilized to form not only part of the solid steel back, but also a part of the socket which receives thebandle, the front strap'forming the other part of said socket.

The absence of shoulders and rivets in the implement obviates the liability of the straps becoming broken, loosened, or pulled off by the severest usage towhich the implement may be subjected.

If it is desired to have the large strap C ou the under or wearin g side of the scoop and the solid steel surface on the inside of the scoopbowl, it can be readilydone by merely turning over the scoop-blade before pressing it into shape. It will be seen,`therefore, that I can at will produce a scoop with the solid steel surface either on the inside or outside of the scoop-bowl.

Having thus described my invention, I claim as newl. The herein-described improvement in the art of manufacturing scoops, which consists in taking a blank of sheet metal of proper size and shape to form the blade and drawing from the metal of the blade a small projection at the top of the blade, welding a narrow strap to said'projection, welding the broad strap to the f'ace of the blade, pressing by means of dies drawn out at the top, the narrow strap Welded 1o and pressure the heated blade into the ultimate to said projection, and the broad strap'welded scoop shape, and opening up a socket for the to the face ot the blade and forming with the handle by inserting a mandrel between the blade a socket for the handle, substantially as ADOLPH T. HEISER.
